There are decentralized (> DEX) and centralized (> CEX) trading platforms and exchanges! The centralized trading platforms such as BitMart, LBank and/or Binance, operate their own economic systems that are not connected directly to other platforms! For this reason, the price on separate platforms can fluctuate differently. The decentralized trading systems such as PancakeSwap or FEGex are merely interfaces that are directly connected to their respective blockchain. The prices on decentralized trading platforms usually do not differ or hardly do so, and mostly due to time delays in the data evaluation. Trust Wallet, for example, usually shows the price of the CEX or DEX that currently has the highest trading volume or an average of that. Since prices vary on centralized exchanges, different prices are often displayed in Trust Wallet or other wallets. The price developments between the CEX's and DEX's are mostly in the same range. Over time, the prices on the various trading platforms are balanced out by what is known as > Arbitrage.
